Abstract
This invention relates to application of eco-friendly starch solution as a quenching medium for heated metal parts fabricated from steel, alloy steel, aluminum and aluminum alloys. Depending on the material grade, critical temperature and desired cooling rate, various types of starch solution can be used and the composition and concentration of the starch quenchant can be tailored to provide the required cooling characteristics for wide range of materials. In particular the starch solutions have the potential to replace quenching oil. The starch solutions are environmentally friendly, having no toxic fumes and no after usage disposal liabilities as compared to oil fumes.
